Understanding Forward Rate Agreements

What is an FRA?

A Forward Rate Agreement (FRA) is an OTC derivative that allows parties to lock in an interest rate for a future borrowing or lending period. Unlike interest rate swaps with multiple payments, an FRA covers a single period with cash settlement at the beginning.

FRA Settlement Formula
Settlement = NP × [(R - FRA) × (days/DCC)] / [1 + R × (days/DCC)]

Why Settlement at Start?

FRAs settle at the beginning of the loan period, not at the end. Since the payment covers interest that would accrue over the period, we discount it back to present value. This is why we divide by [1 + R × (days/DCC)].

Day Count Convention: Most FRAs use Actual/360 (money market convention). This means actual calendar days are used in the numerator, but 360 is used as the year basis.

Pay Fixed vs Receive Fixed

Pay Fixed (FRA Buyer)

Profits when rates rise. You've locked in a lower rate than the market. Hedges against borrowing cost increases.

Receive Fixed (FRA Seller)

Profits when rates fall. You're betting the contracted rate will be better than market. Hedges lending income.

Common FRA Uses

  • Hedging: Lock in borrowing costs for planned loans
  • Speculation: Profit from interest rate views
  • Arbitrage: Exploit rate discrepancies
Reference Rates: LIBOR was discontinued in 2023. FRAs now reference SOFR (USD), SONIA (GBP), EURIBOR (EUR), or TONAR (JPY).

Frequently Asked Questions

A 3×6 FRA covers a 3-month loan starting in 3 months and ending in 6 months. The first number is when the FRA period begins, the second is when it ends. The difference (6-3=3 months) is the loan duration.

The settlement represents interest that would accrue over the FRA period, but it's paid at the start. To be economically equivalent, we discount it to present value using the reference rate. This is called "advance" or "in-arrears" adjustment.

FRAs are OTC contracts (customizable, counterparty risk) while interest rate futures are exchange-traded (standardized, marked-to-market daily). FRAs settle in cash at one point; futures have daily settlements. Both can hedge interest rate exposure.

LIBOR was discontinued in 2023 due to manipulation scandals. FRAs now reference alternative rates: SOFR (USD), SONIA (GBP), EURIBOR (EUR - reformed), TONAR (JPY). The formulas remain the same; only the reference rate changed.

No. The notional principal is never exchanged - it's only used to calculate the settlement amount. Only the interest rate differential is settled. This is why it's called "notional" - it's a reference amount, not an actual loan.

An interest rate swap is essentially a series of FRAs. Each swap period can be valued using this formula. However, swap payments are typically settled in arrears (at period end), not in advance like FRAs, so the discounting differs.
